Scenario

In this Skills Assessment (SA) you will configure the devices in an ever expanding small network. You must configure a router, switch and PCs to support both IPv4 and IPv6 connectivity. You will configure security, including SSH, on the router. You will test and document the network using common CLI commands.

Required Resources

• 1 Router (Cisco 1941)

• 1 Switch (Cisco 2960)

• 2 PCs

• Ethernet/console cables as needed

1: Develop a peer to peer network.

1: Build a peer to peer network.

Topology

Given an IP address and mask of 192.168.25.0/24 (address / mask), design an IP addressing scheme that satisfies the following requirements. Network address/mask and the number of hosts for Subnets A and B will be provided by your instructor.

|Subnet |Number of Hosts |

|Subnet A |2 |

|Subnet B |23 |

The 0th subnet is used. No subnet calculators may be used. All work must be shown on the other side of this page.

|New IP mask (decimal) |255.255.255.128 | |

|Maximum number of usable subnets (including the |2 | |

|0th subnet) | | |

|Number of usable hosts per subnet |128 | |

|IP Subnet |192.168.25.128 /25 | |

|First IP Host address |192.168.25.129 | |

|Last IP Host address |192.168.25.254 | |

|First IP Host address |192.168.25.17 | |

|Last IP Host address |192.268.25.31 | |

Host computers will use the first IP address in the subnet. The network router will use the LAST network host address. The switch will use the second to the last network host address.

Write down the IP address information for each device:

|Device |IP address |Subnet Mask |Gateway |Points |

|PC-A | | | |(5 points) |

|R1-G0/0 | | |N/A | |

|R1-G0/1 | | |N/A | |
